Room Temperature Controller Extension; Connection To Room Temperature Controller - Gira 5142 00 Product Documentation

4.2.4.3 Room temperature controller extension

The device can be used for single-room temperature control. Depending on the operating mode,
the current temperature setpoint and on the room temperature, command values for heating or
cooling control and fan control can be sent to the KNX/EIB. Usually, these command values are
then converted by a suitable KNX/EIB actuator, e.g. heating or switching actuators or directly by
bus-compatible actuating drives, evaluated and converted to physical variables for air
conditioning control.
The room temperature controller is an independent function section of the device. It has its own
parameter and object range in the ETS configuration. Therefore, the room temperature
controller can be switched on or off, irrespective of the push button sensor function.
The controller function section of the device can either work as a main controller or as a
controller extension. As the main controller, the room temperature controller function is fully
switched on and the control algorithm activated. Only the main controller transmits control value
telegrams. A controller extension itself is not involved in the regulating process. With it, the user
can operate the single-room controller, i.e. the main controller from different places in the room.
In this way, any number of operating extensions can be set up.
In this chapter, the functions of the room temperature controller are described as an extension.

Function
The controller extension function can be activated to control a KNX/EIB room temperature
controller. The controller extension function is enabled using the "Controller extension" setting of
the parameter "Room temperature controller function" in the "Room temperature controller"
parameter node.
Typical KNX/EIB room temperature controllers generally offer different ways of influencing or
visualising the room temperature control...
- Switching over between different modes of operation (e.g. "Comfort", "Night" ...) with
different setpoint temperatures assigned to each mode by the thermostat.
- Signalling the presence of a person in a room. The signalling may also be combined with a
configured switchover in the mode of operation.
- Readjustment of the setpoint temperature in levels which are referred in each case to the
configured setpoint temperature of the current operating mode (basic setpoint shift). This
function is only available on a control extension if the main controller is working with
relative setpoint presetting (basic setpoint).
The controller extension is operated using the push button functions of the device ("push button
sensor" function section). In this way, it is possible to completely control a room temperature
controller by changing the operating mode, by predefining the presence situation or by
readjusting the setpoint shift. For this purpose, the buttons of the push button sensor selected
as extension operation buttons must be configured for the "Controller extension" function (see
page 96).
i It should be noted that an extension operation is possible with a button configuration. The
controller extension function must be enabled in the "Room temperature controller"
parameter node. In all other cases, the controller extension function is not operational in
the "push button sensor" function section.
